The detailed land resource inventorization of Chhatra II micro-watershed was carried out to a scale of 1:8000 using IRS imagery and cadastral map of the area as base map aided by ground truth delineation. The contiguous surface soil sampling was done from the grid, each of the size of 6 ha and profile sampling was done at identified sites considering the factors of slope, topography, physiography and land forms. The results which depicted the variability as well as distribution of the aforesaid physical factors within the micro watershed revealed that slope is (gently sloping, 3-5%) about 293 ha, depth (shallow, 25-50 cm) about 369 ha, texture (sandy loam, 48.2%) about 313 ha and gravelliness (gravelly, 39.63%) about 257 ha, hence resulting in 23 soil phase units. The spatial weighted annual average soil loss rate of Chhatra II micro watershed was 290.1 Mg ha-1yr-1 contrary to 343.6 Mg ha-1yr-1 when considering temporal variation under the prevailing agro-climatic conditions. Several soil and water conservation measures such as contour bunding and graded bunding were then proposed.
